CORPORATION OF MISSOURI.

HEADER CONSTRUCTION FOR BOILERS.

To all whom it may concern:

Be it known that I, EDWARD C. MEIER, a citizen of the United States, residing at Phoenixville, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Header Construction for Boilers, of which the following is a specification.

-One object of my invention is to cheapen and facilitate the construction of boiler headers.

:Another object is to so construct my improved header that it can be easily secured to the boiler setting. I

A further object is to make a header in such manner that the main portions can be cut in any desired lengths from rolled 0r pressed sheet metal and joined together, and independent heads can be forced within opposite ends of the joined main portions.

These objects,- and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is an end elevation of a water tube-boiler having headers constructed in accordance with my invention.

Fig. 2 is a sectional elevation taken on the line 2.2 of Fig. 1.

Figs. 3 and 4 are perspective views of two main sections of my improved header.

Fig. 5 is a perspective of one of the independent heads.

Fig. 6 is an enlarged fragmentary View of the upper portion of the front header illustrated in Fig. 2.

Referring to the drawings, 1 and 2 are the front and rear headers which are joined together by water tubes 3. Baflles 4 and 5 are secured to certain of the water tubes 3 as clearly shown in Fig. 2 so that he front header 1 includes two main sections 7 and 8. These sections are made of sheet metal which are rolled or pressed into the shape shown in Figs. 3 and 4 and are each substantially channel shape in cross 7 section and have longitudinally extending top and bottom flanges. Each of these sec- Specification of Letters latent. Patented May 20, 1919,

tions is devoid of any flanges at the opposite ends, and therefore they can be made of any length simply 'by cutting the required length from a long sheet.

The two inwardly turned flanges 9 and 10 of the section 7 are preferably scarfed at their extreme edges as shown at 11. The flanges l2 and 13 of the section 8 are designed to overlap the flanges 9 and 10 as illustrated in Figs. 1, 2, and 6. The sections 7 and 8 with their respective flanges lapping each other as above described, are

joined together. by rows of rivets 14 at the top and bottom. 1

Independent heads 15 are preferably stamped out of sheet metal andeach of these heads l5 has a continuous inwardly extending flange 16 as clearly shown in Figs. 2, 5, and 6. These heads are forced within the opposite ends of the headers to close the end space between the sections 7 and 8.

The flanges 16 of the heads 15 engage the inner surfacesof the sections 7 and 8 and are riveted thereto by rows of rivets 17. These heads are preferablyforced within the headers under great pressure so as to completely form a seal and correspond to the inner contour of the sections 7 and 8. The headers 1 and 2 are tilted as clearly shown in Fig. 2 so that the water tubes 3 connecting them, incline-horizontally.

It will benoted that the rear section 8 of the header 1 has a substantially flatportion 18 forming a part of its top flanges and this flat portion intersects the fiat rear portion 19 at an incline, or in other words at an angle other than ninety degrees. The flat portion 18 therefore does not extend parallel to the bottom lapped flanges lO-and 11.

Since the front header 1 tilts forwardly, I utilize the flat portion 18to provide the holes for connecting pipes or nipples 20 whichlead to the steam and water drum 21. The nipples 20 extend substantially at right angles from the flat portion 18 and radially intersect the drum 21. This permits me to place the drum 21 in such position as not to greatly overhang the supporting structure as will hereinafter be more fully described.

The drum 21 connects with the rear header in the present instance by tubes 22, the tubes entering substantially flat portions 23 of the scribed, the outer end surfaces of the heads 15 and 26 can be made substantially flat and thus provide ample securing space for connecting plates 27 These connecting plates 27 are preferably riveted to the opposite heads of each header and in turn are riveted to uprights or columns 28 which form the main supporting means for the boiler. Thus, the headers 1 and 2 are supported by the columns 28 through the me dium of the plates 27, the connecting means between the plates 27 and the heads being independent of the means which secure the several parts of the headers together.

The front columns 28 therefore can be placed in position to be directly under the axis of the drum 21, thus the front columns directly support the weight of the drum 21 and the front header 1. This relieves any strain on the nipples 20 and furthermore the construction of the header permits the drum to be set so as not to overhangthe main supporting structure to any great extent. This is considered a point of material advantage, since in boilers of this type constructed prior to my invention the connecting nipples from the headers have usually been taken straight out of the tops of the tilted headers, and since the nipples intersected the drum radially, a great portion of the drum overhung the boiler setting. This required an extra amount of room to place the boiler and also required additional support for the extreme forward portion of the drum.

By constructing a header in the above mentioned manner, headers of various lengths can be easily and quickly made up by cutting the desired length of the main sections, joining them together, and after ward forcing in the end heads, thus no special dies are necessary as has heretofore been the custom where the ends as well as the tops and bottoms of the headers were flanged.

I have illustrated in Figs. 1, 2, and 6, hand holes 29 which can be normally closed by hand hole plates 80, however, these hand holes and hand hole plates can be of any desired construction and permit access to the interior of the headers and also to clean the tubes 3.

IVhile I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: l. A substantially rectangular box header for water tube steam boilers of the character described, including two sections cut from continuous lengths of sheet metal which has top and bottom flanges abruptly bent in opposite directions substantially at,

right angles to the main portions of said sections and secured together, said mainportlons of one of the sections having a plu rality of tube holes extending. therethrough; and independent heads secured to the ends of said main sections, substantially as described.

2. A boiler structure including a box header, having two main sections cut from continuous lengths of sheet metal which has rear andtop surfaces of said section, a cross drum extending above the header, and nipples connecting the drum with the header and passing through said substantially. flat portion of the header section, substantially as described.

3. A boiler structure including two columns spaced apart and a tilting box header located therebetween, said headerfineluding two main front and rear channel sections each. having. top and bottom flanges extending from end to end, said flangesoverlapping and secured to each other, independent heads having inturned flanges forced between and secured in contact with the inner surfaces ofthe opposite end portions of said main sections thus providing outer side surfaces for the heads free of obstruction,

and plates connected to said latter surface I and to the adjacent columns, substantially as described. 1

4. A boiler structure including two columns spaced apart and a tilting box header located therebetween, said header inposite end portions of said main section, thus means secured to said outer side surfaces of providing outer side surfaces for the heads the heads and directly to the columns, subfree of obstruction, nipples extending stantially as described.
